Sailun's Terramax RT is a rugged-terrain/hybrid tire positioned between a dedicated all-terrain and a mud-terrain, and its spec sheet lists 39 sizes spanning Load Ranges SL, XL, D, E and F, including 33, 35 and 37in flotation fitments. Sailun states the tire is 3PMS-certified for severe snow at the model level, and LT sizes are pinned for studs — details aimed squarely at winter and off-road use rather than a highway-first design.
Tread depth runs 16/32in on most P-metric/XL sizes (one exception, the 285/55R20, at 14/32in) and steps up to 18/32in on every LT and flotation size — deeper than several established rugged-terrain competitors' P-metric sizes. The treadwear warranty is 50,000 miles / 60 months across the covered sizes, shorter than the 60,000-65,000-mile figures some rivals publish on their own P-metric lines. UTQG is graded 600 A B on P-metric/XL sizes only; Sailun does not publish a UTQG figure for LT or flotation sizes.
Sailun itself is a comparatively newer name in the US 4WD tire market, and the Terramax RT is a newer addition to this library's coverage — this write-up draws on Sailun's own verified spec chart rather than years of aggregated owner-review sentiment the way an established BFGoodrich or Toyo model can. The manufacturer-sourced numbers are real and checkable directly against Sailun's own product page; a buyer prioritizing long-term durability reports heavily should weigh that shorter track record before assuming parity with a longer-established rival.
